Term
___ ___ ___ is a technology that enables electrical power to transmit over twisted-pair Ethernet cable.
Definition
Power over Ethernet (PoE)
Term
One of the key advantages of ___ ___ ___ is the centralized management of power.
Definition
Power over Ethernet (PoE)
Term
___ ___ ___ enables administrators to power up or down remote equipment.
Definition
Power over Ethernet
Term

True or False?

An Ethernet network can have only a single active path between devices on a network.

Definition

True

When multiple active paths are available, switching loops can occur.

Term
___ ___ protocol prevents switching loops from occurring.
Definition
Spanning Tree Protocol (STP)
Term
STP is used with a network ___ or ___.
Definition
bridge
switch
Term
___ ___ ___ is the algorithm STP uses to correct loops.
Definition
Spanning Tree Algorithm (STA)
Term
If the network topology changes, or if a switch port or bridge fails, ___ ___ ___ creates a new spanning tree, notifies the other bridges of the problem, and routes around it.
Definition
Spanning Tree Algorithm (STA)
Term
___ ___ ___ enables a bridge or switch to dynamically work around loops in a network topology.
Definition
Spanning Tree Algorithm (STA)
Term
If a particular port has a problem, ___ ___ ___ can perform a number of actions, including blocking the port, disabling the port, or forwarding data destined for that port to another port.
Definition
Spanning Tree Protocol (STP)
Term
STP uses __ __ Data Units to identify the status of ports and bridges across the network.
Definition
Bridge Protocol Data Units (BPDUs)
Term
__ __ __ Units are simple data messages exchanged between switches that provide the status of ports to other switches.
Definition
bridge protocol data units (BPDUs)
Term
If a BPDU message finds a loop in the network, it is managed by shutting down the interface for that particular ___ or ___ .
Definition
port
bridge
Term
A ____ port accepts BPDU messages but does not forward them.
Definition
blocked
Term
A ____ port is offline and does not accept BPDU messages.
Definition
disabled
Term
A ____ port is part of the active spanning tree topology that forwards BPDU messages to other switches.
Definition
forwarding
Term
A ____ port is not part of the active spanning tree topology but can take over if another port fails. These ports
receive BPDUs and identify changes to the topology when made.
Definition
learning
Term
A ____ port receives BPDU messages and monitors for changes to the network topology.
Definition
listening
Term
Most of the time, ports are in either a ___ or ___ state.
Definition
forwarding
blocked
Term
Using multiple network cables or ports in parallel to increase the link speed beyond the limits of any one cable or port is called ___.
Definition
trunking
Term
The term ___ ___ means essentially the same thing as trunking. It uses multiple cables to increase throughput.
Definition
link aggregation
Term
The higher-capacity ___ link is used to connect switches in larger networks.
Definition
trunking
Term
___ trunking, common with routers, firewalls, VMWare hosts, and wireless access points, provides a simple and cheap way to offer a nearly unlimited number of virtual network connections.
Definition
VLAN
Term
The ___ ___ Protocol, a proprietary protocol from Cisco, ensures that that the switch, network adapter, and OS drivers all support VLANs.
Definition
VLAN Trunking Protocol (VTP)
Term
___ mirroring enables monitoring of network traffic and switch performance.
Definition
Port
Term
To use port mirroring, administrators configure a copy of all inbound and outbound traffic to go to a certain
___.
Definition
port
Term
Port mirroring enables administrators to monitor the ___ and ___ traffic to the switch.
Definition
inbound
outbound
Term
With port mirroring, a ___ ___ examines the data sent to the port.
Definition
protocol analyzer
Term
___ ___ authenticates users on a port-by-port basis.
Definition
Port authentication
Term
The 802.1X standard, often associated with wireless security, specifies port ___.
Definition
authentication
